title: Reactivation of neutron killed mammalian cells by gamma irradiation: the observations, possible mechanism and implication.
abstract: We have observed that combinations of neutron plus gamma ray exposure can significantly increase the colony forming ability of monkey and human cell cultures over the neutron dose alone. The "reactivation" of neutron killed mammalian cells by gamma rays is analogous to observations made in lower eukaryotic organisms and fits the pattern termed "T repair" previously postulated for yeast and protozoans.
